| Subject: [PATCH] seccomp: Add missing compat_ioctl for notify |
| |
| commit 3db81afd99494a33f1c3839103f0429c8f30cb9d upstream. |
| |
| Executing the seccomp_bpf testsuite under a 64-bit kernel with 32-bit |
| userland (both s390 and x86) doesn't work because there's no compat_ioctl |
| handler defined. Add the handler. |
